Systems and methods for providing conditioning to a space within an environment are provided. Such a system may include a solid boundary, at least one air supply aperture configured to direct a conditioned airflow towards the solid boundary, and at least one air return aperture configured to receive a return airflow. At least one of the conditioned airflow or the return airflow may create an air boundary, such that the air boundary and the solid boundary define the space within the environment. At least a portion of the conditioned airflow may enter the space, and at least a portion of the return airflow may exit the space, thereby conditioning the space.
